. BWA, like most mappers, will produce a mapping file in sam-format. Whenever a new sequence is seen, a histogram or table line is printed.

Jul 4, 2020 · For low-coverage data you can speed up your analysis by dropping the -a argument to samtools depth: you don’t need to record zero-coverage bases, they don’t contribute to the total. Passing zero for this option sets it to the highest possible value, effectively removing the depth limit. .
BTW, your usage of "coverage" is non-standard.

should be equal to or greated than the raw depth.
8, samtools would enforce a minimum value for this option. With low-pass data (typically hundreds of thousands to millions of reads) breadth of coverage is generally around 1%, and as such the default behaviour of samtools depth to skip over positions that have zero depth is the most computationally efficient method to count positions with depth >0. bam|in1.
